EMF can generate an XML Schema from an Ecore model. I.e., given a
..genmodel, you can right click and invoke "Export Model..." to export a
schema. Its implemented by org.eclipse.xsd.ecore.EcoreSchemaBuilder.

Definitely you've not clearly stated what you want. Since XMI can be
used to serialize anything, you've basically asked, given an XML file
that's an XMI serialzation of mystery model x, how do I create a WSDL
for it? I'd suggest providing more detail.

your suggestion :-

my question :-
An Ecore model can represent a DataStructure and a set of Operations
where the DataStructure can be serialized as an w3c Schema.In that way
can an Ecore model also be serialized as WSDL Document ?.

Iam attaching the source EMF model serialized as an .xmi and target
WSDL which i want.

No, EMF only has support for generating the <xsd:schema> part of what
you show below. With EMF 2.2, the operations will be encoded as
annotations within that schema. It would be a very interesting thing to
generate a WSDL from the operations; I know very little about WSDL.
Looking at how the EcoreSchemaBuilder works and using the WSDL model, it
definitely should be possible to do something like what you are
suggesting. It would make a very interesting project. Probably folks
would want to do the inverse as well...
